IMPROVEMENT IN NUT-MAKING MACHINES.

Specification iorining'pnrt of Letters Patent No. 45,146, dated Decemberifi, IBG-i.

To all whom it may concern:

Be it known that 1, LEWIS WEcKEssER, of New Haven', in the county of NewHavenand State of Connecticut, have invented a new and Improved Machinefor Making Nuts; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which.-

Figure 1 is a pian or top view of my invention; 1"ig.2, a verticalsection of thc same taken in the line a.' Fig. l; Fig. 3, a verticalsection of the same taken in the line y y, Fig. l; Fig. 4, a verticalsection ot' the same 'taken in the line z z, Fig. l Fig. 5, a verticalsection ofthe saine taken in the line z e', Fig. 1; Fig. 6, a verticalsection of the same taken in the line x w", Fig. 7; Fig. 7, a detachedview ot' two wheels pertaining to the same.

Similar letters of reference indicate like parts.

This invention consists in a novel and sim, ple device for gaging thebar from which the blanks are cut previous to the cutting ott' of eachblank from the bar, so as to insure the blanks being of the same size orof uniform dimensions.

The invention also consists in the peculiar construction and arrangementof parts Whereby the whole opera-tion of punching and forg-Y ing theblanks is brought within a very limited space and a very simple deviceobtained for the desired purpose, and one possessing a num ber ot'advantages, as hereinafter set forth.

A represents a bed-plate, at one end of which there is a driving-shaft,B, from which all the workingparts of the machine are driven.

C is acum, placed on oneend ofthe shaft B, and formed ot' a wheelprovided with a zigzag groove, a', in which a 'friction roller, b, on anarm, D, works, said arm being attached to a slide, E, which works withina grooved bar, F, att-ached to the bed-plate A. The slide E has areciprocating motion imparted toit by means of a cam, C.

G is a rod or shover, which is fitted horizontally in the slide E, andis retained therein by a catch formed of a pin, b', and a spring, c, thepinbeing attached to the end of the spring, and the latter having atendency to keep the pin ina notch, d, in the rod or shovel',

as shown in Fig. 2. In case the rod G meets with any resistance in theprosecution of its work, the pin b will slip out of the notch d in therod and prevent the latter from being bent or broken.

H represents a cutter, which is fitted in a vertical guide, e, on thebed-piece A, and is operated by means of a lever, I, from a cam, J, onthe shaft B, said cani forcing down thc cutter, while a spring,f, raisesit. (See Fig. 3.) Y At one sideot' the guide e there is a lever, K,havinA its fulcruin at. g. t. This lever is operated y means. of aprojection, h, at one side of the cutter H,nearits upper end. (Sec Fig.2.) This projection actsupon the lever KA before the cutter acts uponthe bar from which the blanks are cut,.aud causes the bar which isplaced underneaththe cutter to be compressed to a certain or uniformwidth previous to each cut. therefore causing the blanks to be cut oi'from said bar of equal size. The lever K presses the bar against aplate, t', and when a. blank is cut oli' by the cutter the former dropsdown below said plate and in line withran opening or passage, j, in a.plate, k. This passage j is made ot'spiral form, and the blank is forcedthrough it by the rod -or shover G, which is moved at the proper time bythe cam C, operating the slide E. The spiral opening or passa-ge j turnsthe blank from a horizontal to an edgewise position and forces it into anarrow chamber, L, the bottom otl which is composed of an adj establebar, m,

which is narrower than the chamber L, to admit ot' an opening at eachside for the escape of scales and dirt or trash. (See more particularlyFig. l.) This harm is rendered adjustableby means of set-screws Aninpassin g through oblong vertical holes o o in bars p p, as shown inFig. 2.

The blanks are punched and their face sides rounded in this chamber I.The punch L is operated by a cam, M, on the shaft B, and it worksthrough a xed guide-plate, g, .and within a box, i", which has also asliding motion, and is operated from the sanne cam M. The box fr graspsthe blank and holds it in a proper relative position with the punchbefore the latter is shoved through the blank,thereby insuring thelatter being punched centrally.

The facing punch or tool N is operated from a cam, O, on the shaft B,and simply givesarounded or convex form to the face side of the nut. Theblank is forced from N, directly in front of a slide, P, which isoperated from a cam, Q, on shaft B.

' The slide P shoves the blank on one ot' -a series of arbors, B, iittedradially in a horizontal wheel, S, on the bed-piece, and in such amanner that they may turn in said Wheel. These arbors have each asquare, s, at their inner ends, upon which springs t on the Wheel Sbear, said springs preventing the arbors from turning casually, and eacharbor has a small spur-wheel or Wiper. u, upon it, which adjoin smallcircular collars r. (Shown in Fig. 1.)

The Wheel S is placed on a shaft, T, which extends down through thebed-piece A, and has twowheels, U U', upon it, one of which, U,isprovided with pendent teeth w at equal distances apart, and the otherprovided with notches aX in its periphery, into which apawl, w, catches,to prevent the casual turning of the Wheel S.

V is a rod having a hook, be, at its inner end to Vengage with the teethw of wheel U and rotate the same. This rod V is operated from a cam, W,on shaft BX, the return motion being given it by a spring, 0X. (See Fig.v6.)

X represents a 4shaft underneath the bedplate A, which is driven bygears dx froma shaft, Y, the latter being` driven by gears eX from theshaft B. On the outer end ot' the shait X there are placed two wheels, ZZ', one of which, Z, is provided with teeth fx, and the other, Z', withprojections gx, a'projection being bythe side ot' each tooth'. (See Fig.7.) The teeth fx of the wheel Z serve tol rotate the arbors B, saidteeth engaging with the spur-wheels or wipers u, while the projections11X raise the arbors to free the blanks on them from the bed-piece. rTheblanks are forged on their edges, -while on the arbors 1% by means ofahammer, A',

.operated from a cam, B', on the shaft B, and

each arbor, by the mechanism above described, is turned three times, soas to cause all the sides of the blank to be smoothed or forged underthe action of the hammer. The wheel -S is turned after each blank is4thus forged by means of. the rod V acting on the teeth w ot' wheel U,and by this movement of the wheel S the forged bla-nk is brought Withinrecesses in plates he' at the end of a slide, C', which is operated by alever, D', and a cam, E', onthe shaft BX', driven by bevel-gears fromshaftB.- The plates hx draw the forged blank ofi' from its arbor R Whileasucceeding blank is being brought under the hammer A',

and.V the blank is drawn by the plates hX' over a hole, i", throughwhich it falls intoa passage,

jx, of spiral form, and is forced through said passage by a rod, E',into a chamber, k", the spiral passage fix, turning the blank from anedgewise to a dat position, so that it may receive aiinishing-strokefrom a hammer, F', operated from a cam, G', on shaft B.The

ber la* by means of a forked plate, H', operated by a cam, I',on shaftBX.

' Thus by this arrangement I obtain a nut-v ma'chine which is verycompact, and has all its parts exposedto View, so that the attendant cansee the Whole operation throughout.

Having thus described my invention, Iclaim as 'new and desire to secureby Letters Patentf l. The lever K, arranged relatively with the cutterH, and to operate in connectionthereforth.

3. The spiral passagesj j", for the purpose of turning the nuts,respectively, from a flatwise to au edgewise position, and vice versa,as described.

4. The adjustable barm, forming the bot-` tom of the chamber Z, and ofless Width than the same, to admit of the escape of scales, dirt,

Sto., therefrom, as set forth.

5. The combination of the punch L and box as specified.

6. The horizontal. intermittingly rotating wheel S, provided with aseries ,of radial arbors, B, to receive theblanks and turn the same, sothatits several sides will be consecutively acted upon by thehammer A',substantially 'as set forth.
